Application filed butcher 16. 1924. serial No. 743,971.

fin object bf my invention is to provide a construction for a die casting machine wherein the furnace or crucible is readily removable for the purpose of renewal orut'epair and wherein the furnace or crucible may be removed Without dismantling the machine.

- Other and further objects and advantages of my invention will be described in the specification and defined-in the claims up pended hereto.

In die casting machines, as previously constructed, it has been necessary to partially tear down the machine and to remove the gooseneck in order that the furnace or crucible may be removed for repair or renewal.

According fie this invention a die casting 'machine is so constructed that parts there of which may interfere With removal of the furnace or crucible are pivotally mounted so that the may be swung out of. the way when it is desirable to remove the furnace or crucible or alternatively and more particularly in connection with the larger size units the construction is such that by the removal of certain furnace supports the furnace may be lowered by an elevator truclr and bodily removed.

For a complete description of my invention reference is made to the specification, in connection with the dravvihgs therewith wherein Figure l is a diagrammatic elevation of a form of pivotally mounted die casting inachine.

Fig. 2 1s a diagrammatm elcmtion oi a slightly: difierent form of pivotally mounted till titi

die casting machine and Fig. 3 is a diagrammatic elevation of a further form of furnace mounting.

In each of the figures of the drawings like numerals indicate like parts.

In each of the figures ofthe drawings there a main support 10, furnace housing and support 11, carrying crucible 12. Supported. above crucible 12 is goose neck 13 through the instrumentality of which the molten metal is introduced into the moulds at 14.

In the construction'shown 1 the entire niachineis'" mounted on heavy beams supported at one end on main support 1b and at the other end on furnace housing and support 11. The die casting machine comprises essentially a ram cylinder 16, ram

rod 17, head 18 and guide and lock cylinder mounted in a rigid frame 20 to the forward part of which is secured the dies 21. Goose neck 13 is pivotally mounted at 22 on a pivoted lever 23 carried by trunnions 24: on

cams 15.

In general it is sufficient to mount the goose neck as described since it can pivot sufliciently on its pivoted mountin 22 to allow it to pass dies 21. Should t e construction of the machine be such that it does not allow the goose neck to be gotten out of the way then the frame 20 may be mounted in trunnions 25 so that this may also be pivoted.

With the above construction when it is found necessary to remove the crucible, goose neck 13 is swung out of the way throu h operation of lever 23 and if necessary rame 20 may be swung up and then the crucible 12 may readily be removed without necessitating any dismantling of the unit' The construction shown in' Fig. 2 difiers slightly from that shown in Fig. 1 in that the cylinder 16, guide and lock 19, goose neck 13, etc, are mounted directly on beams 15 which are trunnioned at the back end as at to support 10 and are supported and secured at their front ends on and to lugs 31 formed on furnaceframe support 11.

lVith this construction when it is found necessary to remove the crucible it is only necessary to secure a hoist to member 32, provided for this purpose and pivot the structure about its pivot point 30 which Will remove the obstructing parts from over the 19. All of these members 16 to 19 are r furnace structure and allow access to or the removal of the crucible.

In the construction as shown in Fig.3 which is adapted for the largest size machines the die casting machine is supported on support member 10 and on the furnace frame 11 the cylinder portion not sbgycn,--

being also suitably supportecl fl'l he furnace in this instance ismmountedbver a pit as 40 angl isflsuppo'ft'd on beams 11. With this ""c'onstruction an elevating truck 42 may be Mill simple and convenient means for the m 1 moral of the crucible from a die casting'machine without 'necessitatlng a constructlon wherein it is necessary to tear down the ma newal.

I claimchine fvhe'n the crucible needs repair or re- 1. In a die casting maehine,-a goose neck. and its support mounted over a cruciblein I combination with means pivotuily mounted whereby the goose neck'and its support may be removed from over the crucible by pivotal movement of said means.

2. 'In a die casting machine, a frame on which a ram, die and goose neck are carried, a support to'which one end of the frame 15 pivotal-1y mounted and a support for the other end of the frame.
